Class CellReader<R>

java.lang.Object

cn.creekmoon.excel.core.R.reader.Reader<R>

cn.creekmoon.excel.core.R.reader.cell.CellReader<R>

Type Parameters:

R - the type of the object being read and populated with data

Direct Known Subclasses:

HutoolCellReader

public abstract class CellReader<R>
extends Reader<R>

This interface extends the `Reader` interface and provides methods to add cell converters for reading and extracting data from specific cells in a spreadsheet. It allows converting values from string to specified types and setting the converted values into corresponding fields or properties of an object.
